        TENNECO AUTOMOTIVE TO WITHDRAW EQUITY OFFERING DUE TO WEAK MARKET

Lake Forest, Illinois, May 24, 2004 -- Tenneco Automotive (NYSE: TEN) announced
today that the company is not proceeding with its proposed public offering of
approximately $150 million, or 11.9 million shares, of its common stock as
previously announced on April 16, 2004.

The company has decided against the equity offering due to volatility in the
market and the immediate impact on the company's stock price. The company
determined that concluding the offering at this time was not in the best
interest of its current stockholders.

As a result of withdrawing from its public offering of common stock, Tenneco
Automotive is also withdrawing its tender offer seeking approximately
$130,000,000 aggregate principal amount of its 11 5/8 percent Senior
Subordinated Notes due in 2009 (CUSIP Number 880349AA3).

Based on these volatile market conditions, the company has no intention to
access the markets in the near term. The company will continue to evaluate
opportunities to reduce the interest expense on its 11 5/8 percent Senior
Subordinated Notes, which are first callable beginning in October 2004.

Tenneco Automotive is a $3.8 billion manufacturing company with headquarters in
Lake Forest, Illinois and approximately 19,200 employees worldwide. Tenneco
Automotive is one of the world's largest designers, manufacturers and marketers
of emission control and ride control products and systems for the automotive
original equipment market and the aftermarket. Tenneco Automotive markets its
products principally under the Monroe(R), Walker(R), Gillet(R) and
Clevite(R)Elastomer brand names. Among its products are Sensa-Trac(R) and Monroe
Reflex(R) shocks and struts, Rancho(R) shock absorbers, Walker(R) Quiet-Flow(R)
mufflers, Dynomax(R) performance exhaust products, and Clevite(R)Elastomer
noise, vibration and harshness control components.

This release contains forward-looking statements concerning Tenneco Automotive's
plans. The forward-looking statements are subject to risks and uncertainties
regarding market conditions and other factors that could cause actual results to
differ materially from future results expressed or implied by such
forward-looking statements.
